Aadhaar-based MicroATMs are basically modified POS (point-of-sales) machines that a bank representative (or bank MITR) carries to enable doorstep banking services.
Through it, customers can perform basic financial transactions by only using their 12-digit unique Aadhaar number. In case of inter-bank transactions, they also have to provide their Bank Identification Number.
The machine scans fingerprint or iris as identity proof.

Payments done using MicroATMs are authorized by banks

Currently, over 4 lakh Aadhaar-based MicroATMs are operational across the country.
They support financial transactions like cash deposit, cash withdrawal, funds transfer, and balance inquiry.
Further, there is no service charge involved in using MicroATMs to carry out bank account transactions.
Unlike an ATM, the cash-out/cash-in functions in the MicroATM are performed by an operator.
